WILLIAM RUSH, Q1? CANONSBURG, PENNSYLVANIA,

COMBINATION TOOL.

I Application filed December 13, 1922. Serial No. 606,597.

To all whom it may concern:

Be it known that WILLIAM RUSH, a citizen ofthe United States, residingat Canonsburg, in the county of Washington and State of Pennsylvania,have invented certain new and useful Improvements in Combination Tools,of which the following is a specification.

My invention relates to combination tools, wherein the same may be usedas a socket wrench, valve grinder or drill, the tool being so arrangedas to be changed in an easy and expeditious manner from one tool toanother.

The primary object of the invention resides in the provision of such adevice that is simple of construction, comparatively in expensive ofmanufacture, and highly use ful for a large number of purposes.

With these general objects in view and others that will appear as thenature of the invention is better understood, the same consists in thenovel construction, combination, and arrangement of parts hereinaftermore fully described, illustrated in the accompanying drawings, andpointed out in the appended claim.

In the drawings forming part of this application, like numerals ofreference indicate similar parts in the several views, and whereinFigure 1 is a side elevational view of a device constructed inaccordance with the present invention, the same being shown as employedas a socket wrench.

Figure 2 is a vertical sectional view of the tool shown in Figure 1.

Figure 8 is aside elevational and cross sectional view of the tool, thesame being shown as adapted for the reception of a bore or drillingtool.

Figure 4 is an elevational cross sectional view of an attachment wherebythe tool may be employed as a bolt holder and nut remover. 1

Figure 5 is a longitudinal cross sectional view of a specific form ofnut engaging socket employed in connectionwith the present device.

Figurefi is a side elevational view of an attachment for the tool,whereby engine valves may be rotated.

Figure 7 is a fragmentary cross sectional view through the gear casingof the tool.

F igure 8 is an elevational viewof a reamtained within the ends ofthe'casing by split spring rings 6 received within channels 7 formed ineach end of the said casing.

Journaled within suitable openings in the cover plates 4, which openingsare slightly off center of the platesare the opposite ends of a rotaryshaft 8, one end of which projects outwardly of one of the plates 4 andcasing operating handle 9. The shaft 8 has keyed thereto adjacent oneofthe plates 4,

a large worm gear 10, which gear meshes with a pair of spaced wormpinions 11, therebeneath, which are keyed to a pair of shafts 12transversely within the casing and journaled in suitable openings withinthe cover plates 4. These shafts 12' also have keyed centrally thereon,other worm pinions 13, intermeshing with a worm gear 14 upon the upperend of a pendent shaft 15. This latter mentioned worm 14c rests upon acollar 16, within the casing 1, which collar is formed around an opening17 in the bottom wall of the casing. The casing 1 has externally formedthereon a pendent sleeve or collar encircling the opening 17 therein,and reduced and screw threaded at 19 at its lower end. I

The shaft 15 projects outwardly of the pendent collar or sleeve 18, andhas keyed thereto a thimble 20, which thimble has an angular opening 21in its bottom wall, and directly beneath the end of the shaft 15. Thisangular opening of the thimble receives an upper, angular end of anannular shaft 22, which shaft is maintained within the opening of thethimble by a spring pressed dog 23 carried by the thimble and engagingwithin a notch at the upper end of the shaft.

Loosely engaging over the shaft 22 is a and threaded at 26 for engagingwithin' a-n gagement with the threaded, reduced end 17 of the collar18.v

The lower end of the tube 24 is enlarged internally threaded nipple 27,upon the top side, and at one end ot a right angularly" extendinghousing 28. This end, of the l'iousing is open-and internally screwthreaded for receivinga screw threaded plug-29. The opposite end of-thehousing has a smaller-opening '80 therein, for allowing, a shaft 31 toproject therethrough, the opposite end of thisshatt being reduced as at32 for engaging'within-a" central socket of a plug 29. Adjacent theinner face of this plug, the shaft 31 haskeyed thereto a. small bevelgear 33"intermeshing with a similar gear 84; upon the lower end of thebefore mentioned shaft 22, whereby when this shaft 22 is rotated,asimilar movement will be iinparted'to th'e'shatti31. The projectingendotthe last mentioned slrattihas an angular-socket 85 formedthereonfor thereception of an angular shank 36 of a nut recciving socket 37, orasimilar shank 390i a valve-rotating member 39- or still further, the.shank 40' of a milling tool 451. These elements are more clearlyshown inFigures 5; Band 8, and the angular shank of each has a notch 42 therein,tor'engaging a pivoted doge3 upon the socket end 35 of the shaft 31,this socket having an opening-to allow the head of the dog to passthrough for this; purpose.

As more clearly shown: in Figure 5, the

shank 36 Oct the'nut receiving socket 37 has,

a' longitudinal bore 44- eX'tending therethrough for receiving :oneendof a plunger (15, the opposite end of which carriesan-angular plate d6within the-socket 37." The plurlgerddis channeled as at 47 for allow ingthe same tocsli'de beneath" a transverse pin 4:8 in the bore of'thesocket shank 86. A coiled spring 49 between the plate' iti' and innerwall of "the'socket 37tends to normally project the plate outwardly to aposition as shown, by allowing this plate to moveinwardlywh'en a nutisto be received within the-socket 37. It will 'there 'fore be seen thatwhen a nut is received within the socket,- the same may be unscrewedfrom-its bolt and after being entirely unscrewed therefrom, itwi-l'l'be-projected outwardly otthe socket by the spring pressed plate46.".

Fr m the above description, it will at once be apparent that I haveadapted my tool "to bereadi'ly changed from a socket wrench to avalve'rotating tool, or a milling or cutt'ing tool, merely bypositioning a desired one of these tool'firnplements which? are shown inFigures 5; 6 and 8 in the-socket 35 0f the shaft "31.,

In Figure 3, my tool is shown as being adapted for the receptioniofboringor drilling implements, and in accommodating this tool tor'suchpurposes, a thimble 50 is keyed to the projectingendoft-he shaft 15,which thimble is to med with a pendent externally threaded skirt portion51'. \Vithin this skirt portion 51, are the usual pivotally securedpendent drill engaging arms 52. Positioned at its upper end, over thesaid thiinble is, what may be:-termed,' a -relatively long sleeve 53;internally threaded adjacent its upper endhs atitt'or engagementwith thethreaded skirtportion-51' ofthe thimble 50. The lower endot-th'issleere' converges inwardly as at 55't'oren-gaging the lowcr endsof-th'edrill" receiving arms 52 n'hen the sleeve is screweddownwardly upon thethimble-50 and for properly retaining the drill between the ends ofthese arms. A nut' 56 may be provided upon the screw threaded end of thecasing collarorsleeve 18, to prevent the marring ot these threads-whenthe device is used as a drill.

In Figured, I have shown an attachment formy device, wherebythe same maybe a boltholding and nut removing tool. This attachment includes thetube 56 internally screw threaded atits upper end tor engaging over thereduced, lower, screw threaded end 19 ot'the pendent casing'or sleeve18. This tube hasrthe reduced portion 57 for re ceiving'a shaft 58, the:upper squared end 59 of which engages within the angular opening 21 ofthe thimble 20 shown in Figure 2. The reduced portion 5'. of the tubeextends through an opening in an arm 60, which arm hasa right angularlybent pendent por tion 61 tormedthercon. The end ot'this bent or pendentportion of] the arm has an annular flange or head 62 formed thereon, andthis head'togethcr with the portion. 61 eXtend-swith'ina tube. orcylinder 63 formed vertically u'poucne end'ot anarm 6 1, which armextends beneath therlirst mentioned arm and is et similar dimensionstherewith.

As is clearly shown in Figure 4, a portion of the' reduced end 57 of thetube 56 extends beneath the: opening in the arm 60 and is screw threadedfor receiving thereon a'retainin'g' nut 65, theportion of the end57"of'the tubeabove the arm 60 having: an annular shoulder 66'for closecontact with the upper surface of the said arm 60'. The shaft 58 alsoextendsbeyond the end of the said tube and has k'eye-d thereto anangular sleeve 66; which sleeve has a spring pressed dog 67 for engagingwithin the notch 47 in theshank ofthe nut receivingsocket 37"shown"inFigureli. The lower arm 64 has an angular opening" 68 thereinfor'receivin-gth'e shank 69*of'a bolt head receiving' socket-70'. Theshank of this socket is also provided. with a notch} for receiving IOUthe head of a spring pressed dog 71 carried by the arm forfirmly-retaining the socket therein.

The bolt head and nut receiving sockets are normally maintained in closeproximity to each other by a relatively strong coiled spring 72, withinthe tube or cylinder 63. The lower end of this spring engages upon thehead or flange 62 of the pendent portion 61 of the arm 60, the upper endengaging beneath a cap 73 internally screw threaded for engagement withexternal screw threads on the upper end of the tube or cylinder 63, thiscap having a central opening 74: therein for allowing afree slidingmovement of the portion 61 of the arm 60.

In view of this latter mentioned construction, it will be readilyunderstood that when the attachment shown in Figure 4, is properlyapplied to the tool and after the nut engaging socket has been receivedwithin the socket of the sleeve 66, the arms 60 and 64.- may be sprungaway from each other, whereby the bolt head and nut receiving socketsmay engage over the head of a bolt and the nut respectively.

Any turning movement of the tool handle 9 will occasion av rotarymovement of the shaft 58 for consequently removing the nut from thebolt, the socket 70 preventing the said bolt from turning. In View ofthe spring 72 within the tube or cylinder 63, the arms 60 and 64L may beso extended as to adapt the attachment for any length of bolt.

It is to be understood that the milling tool shown in Figure 8 is to beused for milling the surface of an engine block or the like at a pointadjacent the bolt and nut connect-ions, it being at the present time,

almost an impossibility to properly use a socket wrench for removing thenuts, due

the close proximity of these nuts to the engine blocks. As shown inFigure 8, the milling end of thistube is hollow and has an externalmilling surface, whereby the same may be engaged over a nut for properlymilling the surface of the engine block adjacent the nut for permittingthe employ ment of my socket wrench.

While I have herein shown and described the preferred embodiments of thepresent invention, it is nevertheless to be understood that minorchanges may be made therein, without departing from the spirit on thedriven. shaft, a housing mounted transversely 011 the lower end of thetube element, a shaft rotatable in said housing and disposed at an angleto the shaft in the tube element, driving connections between the shlaftin the tube element and the shaft in the housing, the shaft in saidhousing having a socket formed in the end. portion thereof, and a workengaging element having a shank for removable engagement in said socketadapted to project from said housing in line with the shaft in thehousing.

In testimony whereof I affix my signature.

WILLIAM RUSH.
